Crowded in summer

In short: don’t let the lack of people fool you into thinking the island is “dead”; it just isn’t as lively at these times!

Although there are more tourists visiting at this time than during other months, many restaurants and hotels will be closed or just reopening for business. Beaches may still be relatively empty, but it won’t appear like a ghost town either. By April, that number jumps to 40% as high season begins to approach and Greek Easter brings in additional visitors on top of those planning their summer vacations – practically all businesses open up by then.

 May is the perfect time to visit this idyllic island; it’s bustling without feeling overcrowded. The beaches are brimming with activity, and there’s no shortage of businesses offering their services. After all, who can resist weather that feels like a tropical paradise?

June is a perfect time to visit; the season boasts 90% capacity – meaning it’s bustling yet not overly busy.

 August is highly overcrowded, as it’s the busiest month for Santorini – if you can avoid this period since everything takes more time and effort. Come to September and experience the hustle of High season! The crowds may feel like an extension of August, but it will start to thin out by the end. Enjoy summery weather while you can – check below for more information on what this month has in store. 

October is a bustling time of year, with 70% occupancy rates and cooler weather that still permits swimming in the sea or pool.

December brings a light crowd of just 10% during the heart of the Low season.

From January to February, the chill of Santorini is unmistakable. Although the island remains void of tourists in both months, January usually experiences more rain and colder temperatures than February. Some locals even say that February is typically the coldest month in this picturesque location!

Must-have items for Santorini

When planning a trip to Santorini, it’s important to consider the season and month. During winter (December-February), you’ll want jackets, long sleeves, sweaters, and jumpers; however, shorts or summer dresses are not recommended due to the windy and humid temperatures that can still be quite cold. It is worth noting that January & February tend to be the chilliest months in both Greece and Santorini, with potentially erratic weather conditions – but no extremes!

Winter in Santorini is like the fall/autumn season of prominent European cities such as Paris and London; you never know what to expect, with temperatures ranging from 3°C with drizzle all the way up to 20°C and sunshine. It’s true that there can be a few days where it snows on the island – however, for those accustomed to extreme snowfall, this may seem more like a joke!

In May, say goodbye to winter wear and pack your swimsuits! Santorini’s March climate can be unpredictable, yet nothing that should give you cause for concern. You will likely have days of 15-20 degrees Celsius accompanied by sunrays – a welcomed respite from the cold! Springtime in April normally brings with it balmy temperatures around 25°C along with bright blue skies; however, if you’re looking to take a dip in the sea, then look no further than May. Although still slightly chilly from its hibernation during the Winter months, this is definitely the month for swimming adventures in Greece’s renowned Santorini.

If you are visiting the sunny island of Santorini in May, it’s best to pack your swimsuits and summer clothing, such as bikinis, monokinis, shorts, t-shirts, and dresses. In contrast, if April is your month of choice for a getaway, then be sure to bring jackets and other warm clothing items. It feels like summertime in major cities across Europe during May in Santorini!

Summertime is the perfect season for soaking in the sun and enjoying breathtaking views. From bikinis to monokinis, swimsuits to speedos, and flip-flops to summer dresses, it’s time to have some fun! The weather in Santorini is just right- not too hot (like a desert) but still warm enough that you can wear shorts and skirts year-round. Dare we say it? It might be the best summer ever with temperatures like these!

As we move into the Fall/Autumn months of September, October, and November, days may still feel like summer. However, you should bring a light jacket for those chilly nights. During this time period, most activities will take place on beaches or swimming pools where temperatures are usually warmer than average! By the time October arrives, it is likely to be your last chance to enjoy some fun in the sun without feeling too cold. So make sure you get outside as much as possible while these autumnal conditions permit! 

As the temperature begins to drop in November, swimming may become more difficult to enjoy. You should plan on wearing long sleeves for most days of that month; however, you can also anticipate some spectacularly sunny and warm days with temperatures reaching 20 degrees Celsius! What a treat!

Traveling to 🇬🇷 Greece soon?

I recommend these travel resources for Greece that I personally use:

🏨 Hotels: I have found that Expedia and consistently have the best deals on hotels and resorts in Greece. If you prefer to stay at a vacation rental, check VRBO that is usually cheaper than AirBnB’s added fees!

✈️ Flights: To find the best flight deals to Greece, I always use Kayak. Remember to subscribe to their price alerts for the travel dates you want. Another great alternative for flight deals is Expedia.

🚗 Rental Cars: I always use and highly recommend Discover Cars because it allows me to compare several car rental companies and view ratings on various factors such as overall value, pick-up procedure, agent efficiency, car condition, and total time taken.

🚙 Airport Transportation: For the fastest and easiest way to travel, I suggest arranging a private transfer from the airport and beetween destinations with Welcome Pickups. Honestly, no better way to travel from the airport to your hotel or resort.

🤿 Tours & Activities: For tours and activities in Greece, I highly recommend using either Viator or GetYourGuide. These websites offer a full refund if you cancel your booking 24 hours before the start of the tour, and they also provide excellent customer service in case of any issues.

🚨 Travel Insurance: I always suggest purchasing travel insurance as a precaution before traveling, especially after a recent accident in a taxi in Greece. For short trips, I recommend Travel Insurance Master, whereas for digital nomads, Safety Wing is a better option.

📷 Best Camera for your trip: I always carry with me a GoPro, It’s light, compact, takes great video and pictures, and most importantly, it’s waterproof! You just can’t go wrong with one. If you are interested in higher quality video and photography, I always carry with me on my trips and highly recommend the Sony A7IV which I think is the best travel DSLR Camera out there.

☀️ Biodegradable Sunscreen: Remember to include a good sunscreen to protect yourself from the summer sun. I always use and suggest Sun Bum Sunscreen, which is vegan, reef-friendly, and cruelty-free.

Venture to Santorini during the most optimal months of late March through early June or from early September until late October for an unforgettable experience. During these periods, you’ll be able to bask in warm and sunny island weather as you explore its many treasures like scuba diving, mountain hikes, and ocean swims.

For hot and sunny summer days, a visit to Santorini between June and September is ideal. August boasts the balmiest weather, with an average daily maximum of 30°C and an average low of 24°C. On the opposite end, January offers cooler temperatures; its daily max averages 14°C while its lowest temperature can be up to 9°C.

The year can be divided into two distinct seasons: the warm, arid time from April to October, with high temperatures during July and August, and a colder, wet season from November until late March. January and February are usually the coldest and windiest months of all.

If your itinerary includes traveling during the high season (late June to early September), prepare for warmth ranging from hot to unbearably sweltering. Choose clothing made of light and comfortable fabrics such as linen, lightweight shirts, and shorts – perfect for daytime explorations; or wear a breezy maxi dress or caftan in the evenings when dining out.

January brings winter to Greece, and Santorini is especially frigid. You may experience temperatures as low as 4°C/39.2°F on the chilliest nights! Though most hotels and restaurants are closed during this chilly season, romance still fills the air with its tranquil energy.
